' Application filed March i1, 1909. Serial no. 482,678.

To all whom it may concern."

Be it known that I, CHARLES J. Bone, citizen of the United States. and resident of Syracuse, in. the county of Onondaga and State of New York have invented certain new and useful Improvements in Type- Writing Machines, of which the following is aspecification.

My invent-ion. relates .to paper feeding mechanismfor typewriting machines and machines. v

The main object of my invention, generally stated, is to provide improved devices of the class specified.

To the above and other ends, my invention consists in thefeatures of construction, combinations. ofdevlces andarra ngements of, parts hereinafter described and particularly pointed out in the claims.

The invention is shown as applied to a Monarch typewriting machine but may be adapted to other styles of writing machines.

In the accompanying drawings, Figure 1 .is'a fragmentary bottom plan view of the platen carrier and platen of a Monarch typewriter having my invention, applied thereto. Fig. -2. is a fragmentary bottom plan'view of the paperaprqn or deflector of the machine and of an element applied to said paper apron and adapted to lock the mounted. Figs. 4, 5 and 6 are detail views.

. leading edge stops out of operation. Fig. 3 is a fragmentary perspective view of a rock shaft on. which the leading edge stops are Fig. 7 is a bottom plan view of one of the leading edge stop members. ,Fig. ;8' is a longitudinal sectional view of the stopmember shown in Fig. 7, the spring cli -not being sectioned. Fig. 9 is a vertica sec- "tiona-l view taken on a plane represented by the dotted line m-a in Fig. 1 and looking in' the direction of the arrows at said line, Fig. 9, however, showing the platen carrier turnedoverin' its normal position. Fig. 10

"in Fig. 10.

is a view corresponding with Fig. 9 but showing certain of the parts in different relations from those in which they appearin said Fig. 9, the paper table also being. shown Referring first tojF igs. 1, Sl -and 10, the

platen carrier orcarriage is shown as compr1s1ng a back bar 1 and side or end bars 2.

and 3, said back ban being grooved atits top 'andbottom, to cooperate with the usual ball bearings (not shown). The usual platen 4 is mounted on an axle 5vwhich bears in the end bars and is provided at its ends with finger wheels 6,.one of which is shown. A line spacing ratchet wheel 7, operatively connected with the platen, is adapted to cooperate with other line spacing devices (not shown) to turn the platen inline spacingdirection; Lugs 8 project forward from the back bar 1 and are slotted to receive pairs of arms Sand 10 which are 'pivotally mounted onshouldercd screws 11 and 12, said screws being. 7

supported on said lugs. The arms 9 carry a feed roll rod 13 on which are mounted the sections 14 of the main, feed roller. -'The arms 10 carry a rod 15 on which are mounted the sections 16. of the secondary feed roller. Normally the main and secondary feed rollers are respectively. maintained in A contact with theplaten or thepaper thereon by springs l7'and 18. A rock shaft19,

bearing in the ends of the platen carrier, is provided with lugs 20 which' engage with the beveled ends of pins 21 on the arms .9, when the rock shaft 19 is turned forward, and overcome the springs 17 and 18, swing The springs 23 are secured to the arms 10.

and when the rock shaft-19 is turned for- -ward to release the feed rollers the down-.

ward movement of the arms 10 causes the 'ing the arms 9 and 10 downward and releasing the main and secondary feed rollers.

pressure of the springs 23 on the paper apron to relax. ,The parts thus far described are common to the Monarch machine.

The release rock shaft 19, may be turned or operated by any desired means. The means shown in the drawing were invented application filed November 23rd, 1907, Serial No. 403,531. Said means comprise a crank' arm 24 securedto the end ofthe rock shaft by Edwin E Barney andare shown in his 5.,oppo'site end ofthe rock shaft 19 and having one end secured thereto and the other 19 outside theplateniend bar 3 by a screw 25. Normally a nose 24 on said crank arm is maintained against a stop pin 26 on the end bar 3 by a spring 27 coiled around the of the finger piece 28*. The members 28*- and 31 are toggle elements which normally are angularly disposed; but when the finger piece 28 is pulled forward the toggle elements are straightened as shown in Fig. 10

so that the crank arm 24 and rock shaft 19 which have been turned forward by the finger piece will be maintained in the abnormal positions' shown in Fig. 10, thus locking the main and'supplementary feed rolls in released ositions.

The leading e ge stop devices to which my invention particularly relates comprise supporting arms 33 which are secured by the screws 11 and 12 to the outer side faces of the lugs 8 and extend downward below said lugs, inclining forward somewhat.

also. The lower end portions of the arms 33 are formed with inclined slots 34 which receive screw pivots 35, said screw. pivots being clamped in fixed relation to the arms 33 by nuts 36. By loosening the nuts 36 the screw pivots maybe adjusted both up or down and fore and aft of the machine, and after being brought to the desired positions maybe fixed thereat by tightening the nuts 36. The inner or pivot ends of the screw pivots 35 support a rock shaft 37 which extends from one arm 33 to the other below the arms 10 and is adapted to be rocked on the screw pivots as presently to be described.

The rock shaft 37 is shown detached in F ig.

3. Said rock shaft is provided with a rib or feather 38 which is cut away at twopoints as indicated at 39 'and40; The rock shaft 37' and rib 38 are partially cut awav or notched at intervals as indicated at 41: the notches 4l receiving partsof the leading edge stop devices or members and serving to locate said members in proper positions lengthwise of the rock shaft 37. One of these stop members is shown in detail in Figs. 7 and 8. Each of said stop members comprises a curved hub or collar portion 42 which partly surrounds the rock shaft. and astraight extension 43. which terminates in an angularly disposed end portion or stop is punched and shaped to the desired form.

At either side of the extension 43 are provided fingers 45 which hug the rock shaft, and, with the hub portion proper 42, retain the associate stop member on said rock shaft.

"The ends of the fingers 45 are adapted to be engaged by the rib 38. when the rock shaft 37 is turned, so as to force the stops 44 into contact with the platen. A spring tongue or clip 46 is suitably secured as by rivets 47 to the under side of the extension 43, the free end of said clip engaging the associate notch 41 in the rock shaft 37 and preventing the stop member from slipping along. said rock shaft. By lifting the clip out of the notch, the associate stop member may he slid along the rock shaft 37 and re moved.

.A hook member 48, shown detached in Figs. 5 and 6 formed. preferably of a single piece of sheet metal, partly surrounds the rock shaft 37 andis provided with a curved the notch 40 in the rib 38, the hook member being thereby prevented. from slipping along said rock shaft. l/Vhere the tongue 49 joins the body of the hook member, shoulders 50 are formed, which shoulders are maintained in contact with one side of the rib 38 by a coiled'draw spring 51 (Figs. 1, 9 and 10). Said draw-spring is vertically disposed and the lower end of it is connected to the hook 49,,while the upper end is hooked around the rock shaft 19. As will be understood from Figs. 9 and 10, the draw spring 51 tends constantly to turn the hook member and maintain the shoulders 48 against the rib 38. By this construction the pull of the draw spring is transmitted to the rock shaft 37 so that the rock shaft is constantly tending to turn in the direction of the arrow in Fig. 9-and to force the ends of the stops 44 into contact with the platen.

The apron or deflector 22 is formed With slots 52 which I'LglStGl with the stops 44 and tongue or book proper 49 which engages in through which said steps may move toward and away from the platen. Normally, however, the stops 44 are held away from the platen in the position shown in Fig.9 and the spring 51 is overcome by devices which include a finger 53' shown detached in Fig. 4. The hub portion 54 of this finger surrounds the rock shaft 37 and the extended portion '55 of said finger engages the slot 39 in the rock shaft 37. Shoulders 56, formed at the junction of the extension 55 and hub portion 54, contact with one side of the rib 38, causing the rock shaft to turn when the finger or member 53 is turned in one direction; The notch 39 prevents the finger .53 from sliding along the rock shaft 37.

The extension 55 normally projects upward and forward; from the rock shaft 37 as shown in Fig. 9 and is engaged by a screw or headed pin 57 which projects downward and rearward behind, the extension 55 from a. collar 58, which collar surrounds. the rock shaft 19 and is secured thereto by ascrew "59. The'screw' or pin 57 is screwed or driven into orotherwi's'e secured to the collar '58. The normal position. of i the 'pin 57, it will be understood,'is determined by the normal position of the rock shaft19 whichin turn is positioned'nor'mally by. the spring 27 which maintains the nose 24 against the "stop 26. The spring v 27is stronger than the draw spring 51 so t at the pin 57 forces the extension .55 forward turning the rock shaft 37 through the action of the shoulders 56 on the-rib 38 and extending the ,drawspring until the parts reach the normal position shown in Fig. 9. When, however, the feed rollers arereleased by pushing forward the finger piece 28? and turning the rock shaft .19, the pin 57 is swung rearward to the position'shown in Fig. 10, thereby permittin the draw spring 51' to turn" the rock shaft 3% until the stops 44 have been swung into con-- tact with the surface of the platen a's'shown in Fig. 10-. It will be noted frOmFigfllO that the stops 44 contact with the platen -between the two sets of'released feed rollers.

When an invoice or other sheet, represented in Fig. 10 by the dotted line 60, is intro- 'duced into the machine over the usual paper table 61 and the paper apron 22, said sheet 60 will pass between the platen and the 1e leasedmain feed roller, and its leading edge will contact with and be arrested by the leading'edge stops 44 and will thus be definitely located. The ends of the stops 44 are in a straight line which 'is'parallel-with the axis of the platen so that the pape will be squared or trued by contact with said stops.

Thereafter: the finger piece '28 may be pushed rearward, unlocking the toggle elements and permitting the feed rollers to return to operative position, the main feed.

roller contacting with the invoice sheet (30 y and pressing it against the platen. The

parts are so located and timed that the paper a f or invoice sheet will be clamped againstthe platen by the main feed roller before the pin billing work. e desired to dispense. with the stops 44. I=

57 swings back into contact with the extension 55, the result being that the invoice sheet will be firmly held against the platen by the main feed roller before the leading edge stops 44 move away from the platen to clearthe path andpermit advance or for-. ward'movement of the invoice Sheet.

As is well understood, the leading edge stop devices are useful in some forms of commercial typewriting such as condensed At times, however, 1t may be have, therefore,provided means, 'inthe pres ent instancea closure for the passage ways;

in the paper deflector, for looking or shutting said stops out of operation. Said means are .illustratedin Figs. 1, 2, 9 and 10 and comprise a slidable baror plate 62 which extends lengthwise of the apronor' deflector, 22 .and is-arranged at the under side thereof.

Slots63 formed near the ends of the plate 62 and extending longitudinally thereof receive headed pins orrivets 64 which slidably se cure the plate 62 to the paper apron 22 and so that said-plate, will be frlctionally held in adjusted positions; The-plate 62 is provided with a series of transverse slots 65 at inter? vals, corresponding in arrangement to "the I slots 52in the apron. In the position of the 3 plate 62 shownin Figs. 1, 9 and 10, the slots 65 register with the slots 52' forming con:

tinuous transverse openings so that the stops 44 may pass through both sets 'of slots toward and away from the platen. 'The plate 62 is provided with a downwardly. bent fin-v lger piece 66.at or near one end and when this finger piece is pulled toward the right in Fig. 1 the plate62will beslidrightward and will cover or close the o'- enin s or slots 52 in the paper apron. T ereater when the releasing handleor finger, Piece 28 ispulled forward and the stops 44 are swung upward by the'draw spring 51, said stops will pass through theslots 52but will then contact with the under face of the plate 62 at one side of theslots 65-therein and so 1 will be prevented from moving any farther toward'the platen. By this contrivance the paper releasing devices may-be employed alone or the leading edge stops may be brought into operation concurrently with the paperreleasing devices, at pleasure. Var1ous changes may be made without de-' parting from my invention.
